[Delphinus]

A few years back there was an article on advancedaquarist.com about someone using C. ulietensis (false falcula or double-saddled butterfly) to control majano. On the heels of this I faithfully went and got a pair of C. ulietensis, only to find out the author mis-ID's his butterfly and had, in fact, "true falcula" butterflies (C. falcula, very similar looking but different enough to be noticeably not the same fish). But, be that as it may, butterflies are butterflies and they did go after the majano anemones, within 2-3 weeks they were all gone. After that they went to town on the aiptasia. 2-3 months after that my tank had no aiptasia and no majano. Woot woot! Or so I thought. Unfortunately, flashing back to when I bought the fish, the LFS I bought them from said "Dude are you sure? These things will eat everything in your reef. Please don't buy them." Well, I thought at the time, but so-and-so on advancedaquarist has these and thus so must I! Surely they won't eat EVERYTHING. I'll just figure out what I can and can't have and adjust accordingly. Well, now, 2-3 months in, they're model citizens, and I think, wow, I love these little butterflies. I SHALL NEVER PART WITH MY LOVELIES! ... unfortunately, another month or two, and they start nibbling at LPS. Oooh, ok, into the other tank go the LPS. Then the occasional zoanthid. Meh, says I, zoanthids come and go. I'll be OK with this, they'll stop. Then onto gorgonians. Hey what the .. ? Toss in an SPS frag and poof, destroyed in days. Uhhhmm hmmm. Well, at least they don't eat my clams. Pop! Off a shelf topples a clam, lands upside down, and what do they see? Ooooh, tasty byssal gland, looks like wee little tentacles yum yum. Clam is all "Aiiiee! Someone touched my BYSSAL GLAND OH NOES! I shall retaliate by ... um .. dieing. <gack>"

They never did touch mushrooms though, and they never did touch the leathers that I had. So, I guess it wasn't EVERYTHING although in time it was darn close.

I still have one of my original pair, he's in a FOWLR now.
